5 and useful Improvements in Dust-Guards;

and I do hereby declare the following to be a full, clear, Vand exact description of the invention, such as will enable othersV skilled in the art to which it'appertains to makeand '1o use the same.

My invention relates to an improvementJ in y dust-guards for car-axle boxes, the object Vof the inventiun being to provide a dust-guard which will be strong to withstand all the strain thereon and at-the same time be extremely simple in construction and cheap to manufacture.

With this object in view the invention consists in certain novel features of construction zo and combinations and arrangements of parts,

as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation, illustrating my improve- Fig. 2 is a view in section of the same; and Fig. 3 is a top plan View, partly in section. v

1 represents the lower member of my improved guard, and 2 the upper member. The

3o lower member 1 is madewith the u'ppercurved edge to fit against the lower half ofthe c'araXle and with parallel uprights 3, having tongues 4, secured in grooves in the inner edges of the uprights by nails or pins 4?, and

said tongues adapted to t into grooves in the side edges of the upper member 2 to prevent displacement of the latter, but permit of its free vertical movement. The lower edge of the upper member 2 is curved in the 4o arc of a circle to engage the upper half of the car-axle and, together with the lower member 1, entirelyrsurround the same to prevent any possibility of the entrance of dust and grit into the box. The upper edge of the upper member 2 is grooved to receive a spring 5, coiled between its ends, and the coil is located in the grooved upper edge of the member 2, and the respective ends of the spring.

are slightly bent and disposed in eyes or 5o hooks7 at the upper end of bolts or rods 6,

secured in the parallel uprights 3, as will now be explained.

Each bolt or rod 6 is bent at onerend to form the eye or hook 7 to receive the end of the spring, and the main vertical portion thereof is held in the groove in the upright, between the same and tongue 4,' the latter being notched on its inner edge below its upper end to receive a finger or lug S, formed by bending the lower end of the bolt or rod 6 at right angles, thus securing the same rigidly in place and preventing any possibility of its being withdrawn by the upward tension of the spring.

My improved guard may be made of wood, metal, or composition, and various slight changes might be resorted to in the general `forml and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the precise details set forth, but consider myself at'liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a dust-guard, the combination of two members both movable relative to each other, the lower member having twouprights and an 'intermediate curved face, the upper member having a curved lower face and mounted to slide' in the uprights of the lower member, tongues secured in grooves in the uprights andprojecting into grooves in the upper member, bolts or rods secured in the grooves of the uprights between the same and the tongues, said rods or bolts having fingers or lugs on their lower ends projecting into notches in the tongues, and havin g eyes or hooks at their upper ends at the top of the uprights and a spring bearing between its ends on the upper member and having its ends located in theA IOO the tongues and having lugs at their lower ends proj eotinginto said tongues,and a spring disposed in the groove in the upper edge of the upper member and its ends enga-ging the upper ends of the bolts or rods.

3. In a dust-guard, the combination of two members both movable relative to each other,

' the lower member having two uprights and an intermediate curved face, the upper member having a curved lower face and grooved upper edge, tongues secured in grooves in the uprights and projecting into grooves in the upper member, bolts or rods secured in the ing witnesses.
